Here is what we are seeing. Open any Word document on our server with Word 2011 (mac) results in an excruciating delay. Even a  simple one page document will take over a minute to open up. The same document opened from the desktop of the mac opens in 2 seconds. 

In troubleshooting this I turned on invisibles for my mac and watched the folder on the server where the file resides. Here is what I noticed.

1. If I open that file from a windows computer there is an invisible temp file created for the file that disappears when I close the document. The file opens on the Windows 7 machine with Office 2010 very quickly (2 seconds)

2. If I open the file from my mac with the preview of Word 2016 the same temp file is created and the file opens very quickly. (2 seconds).

3. If I open the file from my mac with Word 2011 it takes over a minute and I don't get a temp file on the server. Closing the document takes just as long.

So, what I am guessing is that Word 2011 is trying to create the temp file, tries for a minute, and finally gives up and opens the file anyway. When I close the file I am guessing it is looking for that temp file and finally gives up after a minute and closes the file anyway. 

Any insights as to what is going on would be appreciated. Our users are very frustrated with this situations.
